Functional imaging with 68Ga-DOTATATE PET-CT is widely employed to detect both primary and metastatic pheochromocytomas and paragangliomas (PGL). We report here a 75-yo woman with an interaortocaval PGL that was diagnosed after hypertensive crisis occurring during the resection of a kidney tumor. 68Ga-DOTATATE PET-CT disclosed pathologic uptake in the abdomen and at the iliac crest. After the resection of the abdominal tumor, with the histological confirmation of PGL, arterial blood pressure and metanephrine levels normalized. Genetic testing was negative. Thereafter, the bone lesion increased in size and became painful, requiring multiple medications. A selective biopsy disclosed a metastatic lesion arising from the renal tumor. The false positive result of 68Ga-DOTATATE PET-CT is discussed.The use of herbal therapies for treatment and management of diabetes mellitus and complications associated with this chronic condition is increasing. Plants contain a bounty of phytochemicals that have been proven to be protective by reducing the risk of various ailments and diseases, including alkaloids. Moreover, alkaloids are known to be among the oldest natural products used by humans for highlighting drugs that play crucial roles as therapeutic agents. The reason for this expanding interest and uses of alkaloids as a part of plant natural compounds-based treatments is that a significant proportion of diabetic patients do not respond very well to conventional therapeutic medication. Furthermore, other explanations to this fact are the cost of medication, side-effects, accessibility, and availability of health facilities and drugs and the inefficiency of these medicines in certain cases.
In this study we aimed to review the literature on the valuable effects of herbs and plants and their isolated alkals.The common antihypertensive angiotensin-converting enzyme (ACE) inhibitor captopril was reported to possess antioxidant and anti-inflammatory effects in different experimental models, diabetic vascular complications arises from increased vascular endothelial inflammation and oxidative stress as well as decreased nitric oxide bioavailability in the vessel walls due to poor glycemic control.
This study aimed to evaluate the role of captopril and gliclazide in decreasing diabetes mellitus (DM) vascular complications caused by decreased cellular glucose uptake and impaired endothelial nitric oxide metabolism, as well as examine the effect of combination on diabetic renal complication and plasma lipid profile.
Adult male Wister rats received captopril (25 mg/kg/day) and/or gliclazide (10 mg/kg/day) by oral gavage daily for one month after induction of DM using streptozotocin (50 mg/kg, i.p., once). Serum glucose and insulin levels, inflammatory mediatory like TNF-α, oxidative stress biomarkers like glutathios an additive effect through enhanced glycemic control and increased anti-oxidant and anti-inflammatory properties above captopril alone.
Captopril showed a promising protective effect against DM vascular complications, at least via nitric oxide modulating effect, antioxidant effect and anti-inflammatory activity that appeared in biochemical and histopathological findings, lipid profile, renal function and architecture improvements. Combining gliclazide with captopril gives an additive effect through enhanced glycemic control and increased anti-oxidant and anti-inflammatory properties above captopril alone.Osteosarcoma (OS) is the basic bone neoplasm with lower survival and poor prognosis. It is distinguished by its offensive nature and metastatic potential. The fundamental death source in OS patients is lung metastasis. In addition, the proliferation and cell migration are thus essential for cancer progression, especially for intrusion and transformation. Several studies have illustrated that 1,25-Dihydroxyvitamin D (1,25(OH)2D) has a critical role in the growth and differentiation of bone. https://www.selleckchem.com/MEK.html However, knowledge about the outcome of 1,25(OH)2D on the progression and incursion of osteosarcoma cells is minimal.
The present study aimed to analyze the effect of different concentrations of 1,25(OH)2D on the multiplication, progression, and intrusion of OS cells and verify the effective doses of 1,25(OH)2D that can decrease the intensity of the disease and improving the prognosis in OS patients.
Saos-2 cells were treated with 1,25(OH)2D (0, 50, 100, and 200 nM) for 48, 72, and 96 hours. Proliferation, invasion, aal trials are needed.
Based on the present results, 1,25(OH)2D by targeting c-Myc and FOXO1 expression displays anti-invasive, anti-migration and anti-proliferative effects on OS cells in vitro. Our findings suggest that effective doses of the 1,25(OH)2D may reduce of the aggressive potential of OS cell line. However, further investigation and clinical trials are needed.Liver disease is global health problem. Paracetamol (APAP) is used as an analgesic drug and is considered safe at therapeutic doses, but at higher doses, it causes acute liver injury. N-acetyl-p- Benzoquinone Imine (NAPQI) is a reactive toxic metabolite produced by biotransformation of APAP. NAPQI damages the liver by oxidative stress and the formation of protein adducts. The glutathione precursor N-acetylcysteine (NAC) is the only approved antidote against APAP hepatotoxicity, but it has limited hepatoprotective effects. The search for new drugs and novel therapeutic intervention strategies increasingly includes testing plant extracts and other natural products. Plumeria pudica (Jacq., 1760) is a plant that produces latex containing molecules with therapeutic potential. Proteins obtained from this latex (LPPp), a well-defined mixture of chitinases, proteinases proteinase inhibitors have shown anti-inflammatory, antinociceptive, antidiarrheal effects as well as a protective effect against ulcerative colitis. These studies have demonstrated that LPPp acts on parameters such as Glutathione (GSH) and Malondialdehyde (MDA) concentration, Superoxide Dismutase (SOD) activity, Myeloperoxidase (MPO) activity, and TNF- α IL1-β levels. Since oxidative stress and inflammation have been reported to affect the initiation and progression of liver injury caused by APAP, it is suggested that LPPp can act on aspects related to paracetamol hepatoxicity. This article brings new insights into the potential of the laticifer proteins extracted from the latex of P. pudica and opens new perspectives for the treatment of this type of liver disease with LPPp.
